A computer that processes analog data is known as an analog computer. Analog computers store information in physical quantities in a continuous format and use measurements to perform computation.

We are always impressed with something so simple can actually be so complex. For example, what would you think goes into an analog computer? Of course, a “real” analog computer has opamps that can do ...

Analog computers have been used extensively in the past, for things like tide calculations, but in the semiconductor era things have mostly gone digital. Even where you have analog elements, like DRAM ...

Although computers are overwhelmingly digital today, there’s a good point to be made that analog computers are the more efficient approach for specific applications. The authors behind a recent paper ...

While digital computers have become entrenched in our daily lives, a new analog quantum computer offers a stark contrast in both its design and capabilities. A team of physicists from Stanford ...

When old tech dies, it usually stays dead. No one expects rotary phones or adding machines to come crawling back from oblivion. Floppy diskettes, VHS tapes, cathode-ray tubes—they shall rest in peace.

Our new tech editor for Analog looks at the evolution of “analog” and how it inadvertently spun off a pop music genre. Operational Amplifiers are exactly that—amplifiers that can perform mathematical ...

A “cheap as chips” open-source Analog Computer can run circles around a Raspberry Pi in solving differential equations and for simulating natural phenomena. To keep costs down, the Anabrid team ...

(Nanowerk Spotlight) The pursuit of faster and more efficient computing has been a driving force in technological progress for decades. As the demand for computational power continues to grow, ...

In the azure waters off the coast of Antikythera, Greece, a chance discovery in the early 20th century transformed our understanding of ancient technology. A sponge diver, exploring the remnants of a ...
